Hackaday ☛ Stretch Goal: 300X Arduino
The Faboratory at Yale University has set a number of stretch goals. We don’t mean that in the usual sense. They’ve been making, as you can see in the video below, clones of commercial devices that can stretch over 300%. They’ve done Ardunios and similar controllers along with sensors. The idea is to put computer circuits in flexible robots and other places where flexibility is key, like wearable electronics.

Raspberry Pi ☛ Raspberry Pi Pico brings junked joysticks back to life | The MagPi #146
To discover how to get data out of the joystick, I had a look at the wires that came out of it. The main unit has two plugs on the end of a (surprisingly long) wire — what looks like a nine-pin RS232 serial connector, and a 15-pin game port connector. The secondary joystick (the one on the right in Figure 1) has a 25-pin connector which plugs into the primary one, which suggests that it just contains switches, and that the first is the brains of the operation. The connector types fit the late-’90s feel of the hardware and give clues as to how we can talk to it, but we can take a look inside to confirm some assumptions.
